Trump Orders Reduction in US-Korea Military Exercises as Seoul Confirms Drills Proceed

US President Donald Trump has ordered the Pentagon to “substantially reduce” joint military exercises with South Korea, citing his “very good relationship” with North Korean leader Kim Jong-un, according to Xinhua News. South Korea’s defence ministry responded that the annual Ulchi Freedom Shield (UFS) exercises would “proceed as previously notified and scheduled.”

The 11-day exercise, which began Monday and runs through August 27, involves approximately 18,000 South Korean troops alongside US forces and personnel from 11 of the 18 member states of the United Nations Command. The announcement comes amid heightened tensions on the Korean Peninsula following two North Korean ballistic missile tests in less than a week.

Trump’s Announcement and Rationale

In a Truth Social post on Sunday, Trump said the exercises are “not only costly, with much of these costs paid for by the United States of America (as usual!), but send a signal that is totally inappropriate and hostile” to North Korea, which he described as “unthreatening and respectful” during his presidency.

“Based on my very good relationship with Kim Jong Un, of North Korea, I am not happy with the fact that the United States has, long ago, agreed to participate in Joint Military Exercises with South Korea,” Trump wrote, as reported by Al Jazeera.

Trump added that “based on the fact that it is too late to cancel,” he had instructed Defense Secretary Pete Hegseth to “substantially reduce” the exercises. He also referenced his recent request to South Korean President Lee Jae Myung to join US efforts toward the “denuclearization of the Islamic Republic of Iran,” stating Seoul replied, “No thanks!”

Seoul’s Response and Exercise Details

South Korea’s Ministry of Defence confirmed the exercises would proceed as scheduled, with a spokesperson stating, “We will proceed as previously notified and scheduled.” The annual UFS exercise, which has been held under that name since 2022, includes 14 battalion-level or higher field training exercises (FTX) this year—slightly reduced from last year’s 17, according to the Maeil Business Newspaper.

Despite the reduction in FTX count, Lt Gen Scott Winter, deputy commander of the United Nations Command, said this year’s drills would be “bigger and better than ever,” according to The Guardian.

North Korea’s Escalating Threat

The order comes at a time of significant concern about North Korea’s evolving military capabilities. North Korea conducted two ballistic missile tests in early August—on August 6 and August 12—with the second launched from the Wonsan area traveling over 700 kilometers, as reported by France 24.

On August 14, North Korea’s Foreign Ministry called the upcoming exercises “a rehearsal for an aggressive war” and warned it would “respond to a new level of threat with a new level of deterrent.”

Military officials from both the US and South Korea have highlighted that North Korea’s battlefield experience in Ukraine has significantly enhanced its capabilities. More than 14,000 North Korean troops have fought alongside Russian forces in the Kursk region, gaining experience in drone tactics, GPS disruption, and cyber attacks. Col. Ryan Donald, public affairs director for US-led commands in South Korea, noted that North Korean soldiers “took those lessons they learned there and brought them back to North Korea, that changes the DPRK capability.”

Retired South Korean Lieutenant General Chun In-bum, who commanded the country’s special forces, warned: “This is a very serious improvement in North Korean capabilities. And we should not take lightly this threat environment.”

Historical Context: Trump-Kim Summitry

This is not the first time Trump has sought to reduce or end the joint exercises. After his historic June 2018 Singapore summit with Kim—the first-ever US-North Korea summit—Trump suspended major US-South Korea military exercises, calling them “provocative, inappropriate and expensive.” The exercises were subsequently redesigned and resumed in modified forms and names.

Trump met Kim three times during his first term: Singapore (June 2018), Hanoi (February 2019), and Panmunjom (June 2019), where Trump became the first sitting US president to set foot on North Korean soil. On Saturday, Trump posted a photo of his Panmunjom meeting with Kim on Truth Social, repeating his claim that they “get along great,” as reported by The Korea Times.

Analysis: Implications for the Alliance

The unilateral nature of Trump’s announcement has raised concerns among allies and lawmakers. Sen. Andy Kim (D-NJ), a Korean American lawmaker, criticized the move, stating: “Decisions about joint exercises need to be made jointly—and not announced unilaterally by social media.”

Emma Chanlett-Avery, director of political-security affairs at the Asia Society Policy Institute, told The Korea Times that “Trump’s announcement suggests that he may be seeking a return to direct diplomacy with Kim, an item of unfinished business from his first term. The problem is that Kim has little appetite for negotiations with Trump, given his increased leverage in recent years.”

Chanlett-Avery added that “Trump’s description of the DPRK as ‘unthreatening and respectful’ is alarming to allies, who have watched the regime steadily improve its missile and nuclear capabilities, while also gaining an additional patron in Russia for its support in the war on Ukraine.”

Cheong Seong-chang, vice president of the Seoul-based Sejong Institute think tank, said Trump could go further if he meets Kim again, potentially deciding to suspend the exercises altogether or reduce US troop levels without consulting South Korea. He argued that Seoul should gradually reduce its security dependence on Washington and move toward securing its own nuclear deterrent capability.

What’s Next

The extent to which Trump’s order will actually affect the ongoing UFS exercises remains unclear. The White House has said Trump remains open to dialogue with Kim “without any preconditions,” and analysts at the Center for Strategic and International Studies have examined scenarios for renewed Trump-Kim summitry, suggesting Kim might seek a meeting with Trump to cement his status as a nuclear-armed state.

Some observers suggest Trump’s exercise reduction could be an effort to divert attention from the ongoing US-Israel war on Iran, which has dragged on for more than five months and left energy costs high—a sensitive economic issue ahead of US midterm elections.

As the UFS exercises proceed this week, the key question remains whether Trump’s unilateral order will fundamentally reshape the US-South Korea security alliance, or whether Seoul’s determination to proceed signals the limits of presidential directives when they conflict with established military commitments.
